【摘要】 主要针对山西省春播早熟区玉米生产积温低、降雨量少、土壤贫瘠的现状,提出了通过增施有机肥和秸秆还田来培肥地力,运用降解地膜减轻环境污染,应用膜下滴灌技术来合理地利用有限的水资源。此外,重点介绍了除草剂的使用以及玉米早、中、后三个主要生长发育时期的管理、病虫害综合防治、隔行去雄增产技术的应用,使这一地区的玉米生产再上一个新的台阶。更多还原

【Abstract】 Aimed at characters of low temperature, low rainfall, poor soil in Shanxi province, the early status of maize production, including of the organic fertilizer and straw returned to increase field fertility, using degradable mulching film to reduce the environmental pollution, using drip irrigation under plastic film to the rational use of limited water resources were put forward. In addition,The use of herbicides and early, middle, late stage of maize growth and development management,integrated pest management, and application of isolation line of emasculation technology, would be make maize production to the new step in this area.更多还原
